gehe in deine lastform.php im Ordner Boxen.
Dort suchst du in der SQL Abfrage.
Standard sieht folgendermaßen aus:
$query = "SELECT a.id, a.name, a.rep, c.erst as last, c.id as pid, c.time
FROM prefix_topics a
LEFT JOIN prefix_forums b ON b.id = a.fid
LEFT JOIN prefix_posts c ON c.id = a.last_post_id
LEFT JOIN prefix_groupusers vg ON vg.uid = ".$_SESSION['authid']." AND vg.gid = b.view
LEFT JOIN prefix_groupusers rg ON rg.uid = ".$_SESSION['authid']." AND rg.gid = b.reply
LEFT JOIN prefix_groupusers sg ON sg.uid = ".$_SESSION['authid']." AND sg.gid = b.start
WHERE ((".$_SESSION['authright']." <= b.view AND b.view < 1)
OR (".$_SESSION['authright']." <= b.reply AND b.reply < 1)
OR (".$_SESSION['authright']." <= b.start AND b.start < 1)
OR vg.fid IS NOT NULL
OR rg.fid IS NOT NULL
OR sg.fid IS NOT NULL
OR -9 >= ".$_SESSION['authright'].")
ORDER BY c.time DESC
LIMIT 0,5";
nach LIMIT 0,5";
ändere dies zu
LIMIT 0,3";
oder halt die Zahl der max Einträge.
